Answer:
6⅓ hours (or 6 hours and 20 minutes)
Explanation:
For Khalil on foot;
Let;
Speed = x miles/hour
Time = 4 hours
Distance = D (miles)
Speed = distance/time
x = D/4
D = 4x miles
For Khalil on the bus;
The bus travels at 6 times his walking rate, therefore;
Speed = 6x miles/hour
Bus follows a route that is twice as long, therefore;
Distance = 2D (miles)
Time = T (hours)
Speed = distance/time
6x = 2D/T
Remember, from above, D = 4x
Therefore,
6x = 2(4x)/T
6x × T = 8x
T = 8x/6x
T = 4/3 hours = 1⅓ hours
Therefore time spent by khalil on the bus = 1⅓ hours or 1 hour, 20 minutes.
Total hours spent on entire trip = hours khalil spent walking + lunch hour + hours khalil spent on the bus
Total hours = 4 + 1 + 1⅓ = 6⅓ hours

Explanation:
The Z disk closer together when the position constantly crossing the bridges. The weight pull forced apart from each other by equal forces.
Sarcomeres are the same in the length. When the lower weight of the bridges occurs than the original weight, the sarcomeres get lengthen.
On the other hand when the weight raises the forces than the weight will increase and sarcomere get shorten.
